->''What was left for Humankind after it lost all of its memories?''

A science fiction novel by HideyukiKikuchi, ''A Wind Named Amnesia'' is a story set AfterTheEnd...sort of. Three years after losing its memories, humanity has been reduced to an almost savage level, with only but the most basic of instincts now driving the lost and confused humans. Wataru, a young man, travels across America, searching for answers to what happens, and why. Along the way, he meets a [[MysteriousWaif girl named Sophia]], who tags along with him. As they travel across the country, they witness how society has changed after being stripped of all reason and logic. And it soon becomes apparent that Sophia may hold a secret pertaining to the fall of humanity...

Written in 1983 and later adapted into a film in 1990 of the same name, it was one Kikuchi's many lesser known works (when compared to the more widely known VampireHunterD and WickedCity).

!!Examples:

* AKA47: Wataru's pistol is clearly a Browning Hi-Power. When the Guardian robot scans it, it's displayed as "Automag 12".
* AliensAreBastards: [[spoiler: Depending on how you view it, the aliens wiping out humanity's memories and reducing them to a savage race could either be seen as played straight with UnfortunateImplications or subverted. Straight because the aliens did this not only because humans were seen as a threat (though considering when they started considering them a threat, it seems to be an overreaction), but also for their own good. As you might expect, by this logic, the aliens see humans going hungry and fighting each other for food and kids losing their parents, along with them setting up {{Human Sacrifice}}s are seen as "for their own good". Subverted because one of them admitted they went overkill and were only trying to stop a possible threat]].
* AmnesiaDanger: To put it simply, everything goes to hell the moment everyone awakens and realizes ''they don't know who they are!''
* AndIMustScream: Amusingly inverted. There ia an AI unit build before the wind blew, capable of managing a ctity. But while it's one of few beings on Earth still capable of higher reasoning it's also trapped in that city with dwindling resources and small staff of other robots, completely unable to stop incoming doom, since it lacks manpower to keep repairing itself and all the infrastructure.
* BadassNormal: Wataru, who retains an almost inhuman martial arts skill even after losing his memories.
** In anime adaptation, he also developed ImprobableAimingSkills, utilising his ''pistol'' as if it was a scoped rifle.
* BigBrotherMentor: Inverted, Wataru is actually much older than Johnny, who is probably 7 or 8 years younger.
* {{Determinator}}: The Guardian robot, in anime adaptation. First of all, it's still doing it's duty years after the civilisation collapsed, but ok, it's just a programming. Then it started chasing Wataru. From Los Angeles to New York. Being almost destroyed and going through reconstruction ''twice''. It takes almost absurd level of abuse before finally being deactivated.
* DidYouJustPunchOutCthulhu: [[spoiler: Wataru uses a bazooka on a StarFishAlien near the end.]]
* {{Dystopia}}: The world isn't entirely in ruins, but without their memories, humanity has abandoned all modern technology and gone back to a simpler, almost cave-man like living style.
* FriendToAllLivingThings: Tonto.
* HerHeartWillGoOn: [[InvertedTrope Gender-flipped]] - [[spoiler: Wataru and Sophia have sex, then ''she'' disappears.]]
* HumongousMecha: ''The Town Guardian [=GT7=].'' Even after it's pilot has long since died, it still continues to patrol the Los Angeles area for any crime.
* IWantMyJetpack: It's 1999 when the action starts and it's at least a year after total collapse of civilization. Yet before the end, humanity used mecha suits (capable of auto-piloting their whole programming), advanced robots, humungous construction machines and fielded at least one AI unit.
* IdentityAmnesia: Waturu wonders constantly what kind of person he was before the wind blew, but he believes he was probably the same.
* KnowNothingKnowItAll: Sophia. She constantly rambles all the time about moral ambiguities over such simple concepts to the point one time she comes off saying ''you should question weather you should stop human sacrifices''.
* UsefulNotes/LosAngeles: The setting for a few of the earlier chapters of the story.
* LaserGuidedAmnesia: The plot of the story.
* MeadowRun: Lisa and Mr. Simpson.
* MeaningfulName: Waturu, which means ''to go from place to another'', guess what Waturu spends his time doing.
* MysteriousWaif: Sophia
* NobleSavage: Quite a few, Little John is one of them.
* OurMonstersAreWeird: Encountered in the sewers of New Orleans, it's confused for a lizard, spider, and snake all rolled into one, with claws, tentacles, and suction cups.
* PsychicPowers: Displayed by a crazed patient near the hospital where Waturu meets Johnny. [[spoiler: Sophia is shown to have some sort of telepathy.]]
* RealityWarper: [[spoiler: Sophia does this in the sewers.]]
* RedEyesTakeWarning: Guardian's camera lense is red.
* SceneryPorn: From Los Angeles, to Las Vegas, a futuristic utopia, to New Orleans.
* ShoutOut: Quite a few.
** The girl met in the future city near the Mojave Desert is named ''[[TheSimpsons Lisa Simpson]]''.
** TwentiethCenturyFox is mentioned.
** A portrait of ''Philip Marlowe'' and ''Terry Lennox''.
** MickeyMouse (or at least a crude imitation) can be seen in one of the illustration pages.
* SplitPersonality: [[spoiler: The youth met in the Las Vegas strip]] who is innocent and gentle one moment, but immediately turns into cold blooded killer a the drop of a hat. And the killer personality still retains his memories!
* SuperPersistentPredator: The Guardian robot (at least in anime adaptation), who chased Wataru all over the way from San Francisco to New York.
* WiseBeyondTheirYears: Johnny; however, it's explained he underwent gene therapy that gave him high intelligence, and luckily allowed him to keep his memories.
* WomanInWhite: Sophia again.
